Claims priority, application Germany Aug. 6, 1956 6 Claims. (Cl. 242-55.16)

The invention relates to the reeling of web materials,

and relates more partcularly to methods of and means for the continuous reeling, for instance, for storing or transportation of smooth spread out webs of fabric or of synthetic or other materials. The nvention is particularly suited for the wet treatment of web material, such as dyeing, bleaching, de-sizing, or the like, as well as for the dry handling of such material.

It is among the principal objects of the invention to provide tor reeling of web material in a roll trait: in such a manner that the web is wound onto a roller in a double layer. I

Double Iayer rolling has been practiced in the past, but was characterized by the need for an artifici'al fold.

It is therefore a further object of the invention 'to provide for double layer winding without the need for any artifical fold, thereby simplifying the methods and machinery required for the purpose.

Broadly speaking, this is accomplished by providing a group of rollers, each slotted or otherwise formed for the threading through the rollers of the web, and each roller is positionable among a plurality of stages within the roll train. The instant invention ofi"ers the advantage of stonng the Web substantially for any length of time simply by the control of the reeling speed.

Further objects and advantages of the invention will be set forth in part in the follwing specification and in part will be obvious therefrom without being specifically referred to, the same being realized and attained as pointed out in the claims hereof.

In the accompanying drawings,

Fig. 1 is a schematic view of a roll train for the winding process; Fig. 1 is divided into a plurality of steps A, B, C, D, B, and F, the step A illustrating the material passing through the rollers unwound, the step B showing one roller winding material, the steps C and D showing all the rollers moved to the right for one stage, one roller winding and the previously wound roller unwinding, the steps E and F showing the reeling after the end of the web has been reached; and

Fig. 2 is a schematic view illustrating a specific exemplificaton thereof.

In accordance with the invention, as diagrammatically illustrated in Fig. 1, there is provided a series of rollers a each positionable among a plurality of stages, such as for instance four stages designated I, II, III, and IV. The vafious phases of the process, and the function of the rollers during the process, are shown in separate steps designated A, B, F. The four rollers a are disposed in the stages I IV. Bach roller a is provided with a slot b whch forms a guide for the web e of material and which causes winding up of the web 011 the external surface of the roller when the roller s turned. The slots b may be formed, for instance, by making the roller of two parts.

The row of rollers a of the first step A of Fig. 1 shows the roll train with the web b threaded through all the -rollers and suspended substantially straight. The

stage II is the turning stage for all the steps, so that any roller when it is positioned in the step II may be turned by any suitable means.

Por winding, the web Will be severed between the stages II and III, and the roller of the stage II be energized for rotation whereupon the material will be wound onto the external surface of the roller of stage II (as shown in step B). After a desired .amount of material has been wound onto the roller, all of the rollers will be transferred, each to the next higher stage (to the right,in Fig. 1). Such transfer may be done mechanically or by hand, and the return of the rollers later on to the original stages may also be done by hand.

After the rollers have been moved for one stage, an empty rol1er will again be placed in the stage II. The roller in the stage 11 Will be turned, thereby winding material onto its external surface, drawing the material not only from the supply (from the left of Fig. 1), but also by unwinding material from the roller that is now in the stage III, as shown in step C. After a desired amount of material has been wound in double layer form onto the roller that is in the stage II, all the rollers Will again be moved,to the right, to the next stage (as shown in step D); in the step D, an' empty rller Will be Placed in the stage II which will be wound With a double layer, namely drawing material from the roller of stage I and unwinding material from the roller of stage III; the free leading end of the web of the roller in stage IV is transported avvay to the right. In this manner, there will be wound onto each successive roller at the stage II a double layer of web material, wi thout need for any special means for the double layer formation (steps C and D). v

In this manner, each roller Will thereby be wound with a double layer of web material in succession, and thereafter again be unwound.

The empty rollers may then be brought back to the original position at the entrance of the roll train, or there may be used a large number of rollers for the successive progress through the stages of the roll train.

After the end of the web c has been reached, it will be sewn, for instance by band, onto the end of the next adjoining web. In this manner there may be accomplished a sen'es of windings without standstll, and the length of time of the winding in the two winding stages II and III may largely be regulated by controlling the speed of rotaton.

In Fig. 2 there is shown a practical embodiment of the invention, wherein the winding stage II and the unwinding stage III are positioned in a closed casing d in order to subject the web to treatznent by liquids, vapors, or the Iike. The casing a is provided on both opposite sides. each With a slot for the passage of the web, and with a door structure such as opposite removable flaps 1 to permit the movement of the rollers among the stages.

The drive for the roller in stage II is accomplished by means of a frctional driving mechanism such 215 a driven fn'ctional tiltably journalled driving cylinder g.

In order to brake the speed of rotation of the roller in stage III during the unwinding, there is provided a brake mecham'sm such as a tiltable journalled roller h whch abuts against the outer surface of the Windings of the material, and which is drven by the material and is connected by a flexible means such as a bel; to a brake i. The brake i controls by means of the belt the speed of rotation of the roller h, and thereby, in turn, the roller h controls the unwinding speed of the roller a in the stage III.

The stepwse shifting of the rollers from stage to stage the roiler may be taken apart in the stage IV and the parts transported separately to the stage I and be reassernbled in stage 1.

We Wish it to be understood that we do not desire to be limited to the exact details of construction shown or described, for obvious modifications will oecur to a pers0n skilled in the art.

Having thus described the invention, what we c1aim as new and desire to be secured by Letters Patent, is as follows:

1. A method for the continuous storing and transporting, respectively, of a web of material by means of a train of more than two slotted rollers, 2111 the ro-llers of the train being adapted to be simultemeously shifted for positioning rnong successive aligned stages including a drive stage wherein each roiler in succession wii1 be rotated, the steps comprising, threading the web through the ro1iers, severing the web between two successive ro1lers in the train one being positioned in a drive stage and the other after the drivestage, winding erre portieri of the web onto the rolier in the drive stage, thereafter shifting said roliers to the next succeeding stage and rotating the roller which has been shifted to the drive stage whereb'y the rolier in the drive stage wil wind unto its exterior surface a second portion of the web and will unwind the said first portion of web 01 the roller positioned in the stage after the drive stage, thereby winding the material in a double layer.

2. In a method as claimed in claim 1, the step comprising transporting the free leading end of the web away after it has been unwound from the ro11er of the last among said successive stages.

3. In a machine, for use in continuously storing and respectively transporting a web of materia]. fed thereinto, the -combination of a roller train including a pluraiity of roilers located in a series of more than two successive stages each spaced apart from all the other stages, and

all the stages being aligned, and inciuding a drive stage wherein a roller is rotated, each ro11er having suspension means for threading therethrough the web for web suspensi-on, and alt of said rollers being simultaneously shiftable in (me direction between successive stages, means operable tor rotating the roller positioned in the drive stage, the roller in the stage following the drive stage being turnable, whereby the roiler in the drive stage wil1 wind one portion of the infed web materiai and unwind another portion of the web material from the roller in the stage following the drive stage, and thereby will wndsaid one and other portions in the drive stage into a double layer.
